Port wine grading system, how does it work ?
 

Mario,

the system is explained in the book I mentioned: "Port and the Douro" by
Richard Mayson, page 64. It is a bit to lengthy to retype here ;-)
Please note that this is not a grading system for the wine, but for the
vineyard, the plot of land where the wine comes from.

More info may be found at the site of the "Instituto do Vinho do Porto",
e.g. http://www.ivp.pt/uk/Viticultura/

(also in Portuguese or French, so you can find out which is more similar :-)

Port wine grading system, how does it work ?
 

if you're interested in comparing the wine, your best bet is to go to
www.winespectator.com and either search for articles on Port, or else enter
the names of the specific wine you're interested in.

No, 4 pages.

Not in detail. As I said, I am not going to retype, but one short example
from the book willl do:
"Soil type: a maximum of 100 points is awarded to schistous soils, minus 100
for soils described as 'transitional', minus 250 for granite and minus 400
for alluvium. The latter are virtually non-existent, since the valley floor
was flooded in the 1970s."

BTW, he also gives a list of the major quintas with their ratings. Not
surprisingly, being "major" most of them are 'A'.

The grading system, "Método de Pontuação", was devised in 1947. It mainly
serves to establish the so-called "benifício". See e.g.
http://www.cirdd.pt/pt/i_comunicado.htm where you will also find that a
revision of the system is being considered.
